- steel platforms for passenger equipment cars.

The object ofmy invention is to provide a steel platform for use upon passenger equipment cars of thekind having wood sill underframes, which will be ofa strong, safe, reliable and simple construction, and adapted for use in; repairing wood sill passenger equipmentcars, such as "coaches, sleeping cars, baggage cars, etc., of either new'constructionor of old construction.

Myinvention consists in the novel construction of partsand devices and in the novel combinations of parts and devices which I employ to practically accomplish this object or result and as herein shown and described and more particularly specied in the cla ms- One form of my invention comprises two pair ofwide flanged rolled steel channels,

commonly known as ship channels, with their-upper flanges fitting against and secured to .the longitudinal wood SlllS of the car frame and extending through and se-.

cured tothe body bolster and connected to gether by ties riveted to the lower flanges of the ship channels, one or more of the ties having brace extensions connected to intermediate sills of the car frame. ship channels of the steel platforms are further connected together and to the end sill of the car and to the vestibule end sill by transversely extending angle plates.

In the accompan ing drawing forming a part of this specification, Figure l is a plan view of a steel platform embodying my invention, showing a portion of the body bolster of the car, the wood sills of the car frame being removed. Fig. 2 is a central, vertical, longitudinal section of a portion of a car underframe with my improved steel platform applied, the section being taken on line 2-2 of Fig. 1. Fig. '3 is a detail front elevation, looking from line 3-3 of Fig. 1, the buffer stems and draw-bar of the coupler being shown in section. Fig. 4

The

is a vertical section of the car frame on line 44 of Fig. 1. I In the drawing, 1, 1, represent the sid s lls of a passenger equipment car underframe, 2, 2,.the cen-ter sills 3, 3 and 4. 1 intermediate sills, the same being of the ordinary wood construction.

5 is the body bolster, it being preferably of the cast steeldouble type or provided with two bolster members 5 and 5" cast integrally together.

6 is the center plate, also preferably integral with the bolster and 7 is the openmg to receive the center pin.

8 is the end sill,- 9 the vestibule end sill, 10 the end floor plate, 11 the buffer plate, 12 the buffer stems, 13 the. buffer and 14 the draw-bar of the coupler.

My improved construction of steel platform comprises an inner pair of Wide flanged rolled steel channel beams 15, 15, such as are commonly termed in the trade ShlP channels, an outer pair of similar wide flanged rolled steel channels 16, 16, the upper flanges 17 of which channels 15, 16 fit flat against and are rigidly secured to the lower faces of the wood sills 2, 3 of the car frame by bolts 18. The inner pair of channels 15, 15 have their flanges facing outwardly from each other or in opposite dimotions to enable the cheek plates or stopoastings of the draft rigging to be better secured to this inner pair of platform channels. Theouter pair of platform channels 16, 16 are preferably, for symmetry, faced in the same. manner, or. with their flanges in opposite directions from each other.

' The wide flanged steel channels 15, 16 are braced and connected together, by transversely extending tie plates 19, 20, the front plate 19 being preferably located at the front ends of the channels 15, 16 and riveted to the lower flanges 21 of the channels. The rear tie plate 20 is connected to the lower flanges 15, 16,'preferably directly under the end. sill 8 of' the car frame and this tieplate 20 isprovided with upwardly extending brace extensions 20, the ends of which are secured by bolts 22 to the outer intermediate sills it of the car frame. The wide flanged platform channels 15, 15 are further connected and braced by brace members 23, 24:, each of which is furnished with right angle ends 25 secured by rivets to the upright web of the channels 15, 15.

The inner pair of Wide "flanged platform channels 15, 15 are preferably longer than the outer pair 16, 16 and are preferably extended through both the front and rear members 5 and 5? of the double body bolster 5 and are rigidly secured to the body bolster by vertically and horizontally extending rivets or bolts 26, 27. y

The flanges of my steel platform channels 15, 16 are preferably substantially equal in width to the thickness of the wood sills of the car frame to which they are secured, thus giving them a very firm and ample bearing against the sills and adapting them to form with the sills a unitary structure of very great strength and rigidity against all kinds of strains to which the same may be subjected in practical use.

The transversely extending abutting plate 28 rests upon the upper flanges of the channels 15, 16 and is securely riveted thereto and abuts at its rear edge against the front edge of the bolster 5, thus preventing the two. inner channels 15, 15 which extend through the bolster from being driven backward under extreme buffing stresses. The two outer and shorter channels 16, 16 preferably abut at their rear ends against the front upright web of the bolster casting. To further anchor the two inner platform channels 15, 15 in place against pulling stresses, I provide an abutment plate 29 which is secured by rivets or bolts 30 tothe channels at' the rear ofthe bolster and which abuts against the rear face of the bolster.

Transversely extending angle irons 31, 32 are secured to the upper flanges of the channels 15, 16 by rivets 33 and to the end sill 8 by bolts 34 and vestibule end sill 9 by bolts 35, thus tying together the channels 15, 16 and firmly connecting the same with the front end sill of the car frame and the vestibule end sill and tying the whole structure together.

ll claim v 1. In a steel platform for railway passenger equipment cars, the combination with the body-bolster and wood sills of the car frame, of an inner and an outer pair of oppositely faced, flanged rolled steel channels fitting at their upper flanges against and secured to the center and intermediate sills of the car frame and secured at the rear ends to the body-bolster, tie-plates connecting all of said steel channels and bracing the same, and a tie-plate of substantially inverted channel shape secured to the inner pair of said channels and located entirely between and arranged to brace the same.

52. In a steel platform for railway passener equipment cars, the combination with the body bolster and wood sills ,of the car frame, of an inner and outer pair of oppositely faced \vide flanged, commercially rolled steel channels fitting at their upper flanges against and secured to the center and intermediate sills of the car frame and secured at their inner ends to the body bolster, and tie-plates connecting and bracing said steel channels, one' of said tie-plates having brace extensions secured to an outer pair of intermediate sills of the car frame, said tie plate being secured to the under sides of the lower flanges of each of the channels, substantially as specified. ,3. In a steel platform for railway passenger equipment cars, the combination with the body bolster and wood sills of the car frame, of an inner and outer pair of oppositely faced wide flanged, commercially rolled steel channels fitting at their upper flanges against and secured to the center and intermediate sills of the car frame, and secured at their inner ends to the body bolster, and tie-plates connecting and bracing said steel channels, one of said tie-plates having brace extensions secured to an outer pair of intermediate sills of the car frame, and being secured to the under sides of the lower flanges of each of the channels, said inner pair of channels being longer than the outer pair and extending through the body bolster, substantially as specified.
